Abstract
Abstract The present invention provides a syringe for the administration of small amounts of high viscosity fluid having a barrel and a delivery needle having substantially the same inside diameter. It is preferred that the barrel comprise a stainless steel tube. A generally cylindrical housing member having openings at each end of the housing and threads on one end for attaching the housing member to the barrel. An adapter member, secured to the other end of the housing member, receives and supports the other end of the barrel. A cap secures the adapter member to the other end of the housing member. A plunger is adapted for axial displacement within the barrel, and has a plunger tip which is chemically inert with respect to the fluid and which is adapted to slidingly engage the interior surface of the barrel and to seal the fluid within the barrel. A finger grip and a thumb grip facilitate movement of the plunger relative to the barrel. In one embodiment, the syringe may be directly filled with a highly viscous fluid such as silicone fluid by positioning the syringe within an adapter fitted to a bottle containing the fluid. In another embodiment, the fluid to be injected is contained within disposable prepackaged carpules which may be inserted into the syringe.
